An overview of the Maxillaria porrecta Lindley complex is presented for the Venezuelan Guayana, the Guianas, and northeastern Amazonas. Maxillaria colemanii Carnevali & W. Fritz is proposed, described, and illustrated as a new taxon in the complex. Within the complex, the new species is easily distinguished by the presence of leaf blades on the 1-2 innermost sheaths enveloping the pseudobulbs, proportionally narrower perianth segments, an almost unlobed labellum, and the lack of wax on the underside of the leaves. A key to the species of the M. porrecta complex for Venezuelan Guayana, the Guianas, and northeastern Amazonas is proposed and comments and distributional notes on the members of the complex are provided. Maxillaria amazonica Schltr., M. taracuana Schltr., and M. lactiflora Pabst are all included in the synonymy of M. kegelii Rchb. f. Maxillaria brunnea Linden & Rchb. f. is included in the synonymy of M. porrecta Lindl.
